基于卫星观测数据的地球重力场探测技术发展趋势分析
Analysis of Earth Gravity Field Detection Based on Satellite Data
摘要
Abstract
Based on the statistical analysis of the published global gravity field models,the development trend of gravity field models is summarized.In order to study the future development of the gravity field detection technology,the characteristics and limitations of Lageos,gravity satellites and altimeter satellites for earth gravity field detection are analyzed according to the inversion results of the gravity field models derived from real satellite observation data.Finally,some new payloads for the earth's gravity field detection,such as laser rangefinder,atom interferometer gravimeter,interferometric SAR altimeter,are introduced and their possible application effect are discussed.The research above can provide a reference for the future development of earth gravity detection technology.关键词
